A T-shirt stand on the boardwalk recently sold 6 purple shirts and 9 shirts in other colors. What is the experimental probability that the next shirt sold will be purple?

Answers

Answer:

2/5.

Step-by-step explanation:

To find the denominator, you add all of the times the experiment has been done.

6 + 9 = 15.

Then, since they're asking about purple shirts, you put that as the numerator.

Making it 6/15.

To simplify, divide both sides by 3, making it 2/5 simplified.

The solution is, 2/5 is the experimental probability that the next shirt sold will be purple.

3. a trader sold an article at a discount of
18% for GHC828.00. If the article
was initially marked to gain 25%
profit, find the:
a) cost price of the article
b) discount allowed.​

Answers

Answer:

GHC757.317

GHC181.756

Step-by-step explanation:

Given that :

Discount on sale = 18%

Sale price at 18% discount = 828

828 = 100% - 18%

828 = 82%

The cost at 100% can be represented as :

828 = 0.82

x = 1

Cross multiply :

828 = 0.82x

x = 828 / 0.82

x = 1009.7560

The price 1009.7560 includes a marked gain of 25% ; Hence, cost price of the article is :

(100 - 25)% * 1009.7560

0.75 * 1009.7560

= GHC757.317

Discount allowed :

1009.7560 - 828

= GHC181.756

To do this, we make use of sine law which is represented as:

what number must you add to complete the square? x^2+28x=11

Answers

x²+28x+11

To complete 2ab of (a+b)²

2ab=28x2x(b)=28xb=28x/2xb=14b²=196

196 must be added on both sides to get complete square as (x+14)²

Answer:

196

Step-by-step explanation:

Given equation:

[tex]x^2+28x=11[/tex]

Step 1

When completing the square for an equation in the form ax²+bx+c=0, the first step is to move the constant to the right side of the equation.

This has already been done in the given equation:

[tex]x^2+28x=11[/tex]

Step 2  

Add the square of half the coefficient of x to both sides.  

This forms a perfect square trinomial on the left side:

[tex]\implies x^2+28x+\left(\dfrac{28}{2}\right)^2=11+\left(\dfrac{28}{2}\right)^2[/tex]

Simplify:

[tex]\implies x^2+28x+14^2=11+14^2[/tex]

[tex]\implies x^2+28x+196=11+196[/tex]

[tex]\implies x^2+28x+196=207[/tex]

Step 3

Factor the perfect square trinomial on the left side:

[tex]\implies (x+14)^2=207[/tex]

We have now completed the square and can go onto solving the equation.

Therefore, 196 must be added to both sides of the equation to complete the square.

Answers

Answer: There were 6 guides on Sunday.

Step-by-step explanation:

I suppose that this is a question about equivalent ratios:

It is said that the company had the same ratio of tourists to guides on Saturday and Sunday.

RATIO OF TOURISTS TO GUIDES:

SATURDAY: 120 : 18

SUNDAY: 40 : ?

Divide 120 by 40:

120/40 = 3

Divide 18 by 3:

18/3 = 6

Therefore:

SAT: 120 : 18

SUN: 40 : 6

Check it by multiplying both numbers in the ratio 40 : 6 by 3:

40 • 3 : 6 • 3

= 120 : 18

(You get the ratio from Saturday)

PLEASE SHOW WORK/EXPLANATION FOR BRAINLIEST

Answers

answer: 151.25 cm^2
explanation: separate into rectangle and semi circle. you can find out the diameter and radius of the semi circle by subtracting the 6 from the top from the 16 of the bottom because the diameter of the circle plus the 6 take up the same length.
16 - 6 = 10
for radius divide by 2
10 / 2 = 5
area of rectangle: l x w
16 x 7 = 112
area of semi circle: 1/2(pi)r^2
1/2(3.14)5^25 = 39.25
add up the two areas to find the area of the entire figure
112 + 39.25 = 151.25

Answer:

151.25cm

Step-by-step explanation:

First split the the shape into two, a rectangle and a semicircle.

Let's begin with the rectangle. The formula for the area of a rectangle is

A = l × w

A = 16 × 7

A = 112

Now we move onto the semicircle. We know that the length of the long side of the rectangle is 16. Because of the markings, we know that the missing portion of the 6cm line is 16 as well. That means that we would do 16 - 6 to find that small missing length. It gives us 10cm which will act as the diameter for the semicircle.

The formula for the area of a semicircle is

A = [tex]\frac{\pi r^{2} }{2}[/tex]          (fill in what you know)

A = [tex]\frac{3.14 (5^{2} )}{2}[/tex]     (The radius is half the diameter. So 10 ÷ 2 = 5)

A = [tex]\frac{3.14(25)}{2}[/tex]     (Solve what's in the parentheses first)

A = [tex]\frac{78.5}{2}[/tex]          (multiply pi and 25)

A = 39.25

Now all we have to do is add the two areas to get the combined area of the whole.

A = 112 + 39.25

A = 151.25

- (x + 1)² = 4 ( multiply both sides by - 1 )

(x + 1)² = - 4 ( take the square root of both sides )

7x/9 = 49 multiply both sides by 9

7x = 441 divide by 7

Write the equation of a straight line that passes through the point (3,1) and is parallel to the line y=2x-1

Answers

Answer:

Step-by-step explanation:The new line will be parallel to the line represented by y =2x +2

The equation y = 2x + 2 is written in slope- intercept form (i.e. y=mx + b) where m represents the slope.  So the slope of this line is 2.   A line parallel to y = 2x + 2 will have the same slope.  This means the slope of the new line will also be 2.  

To determine the equation of the new line, we can use the given point  to find the y intercept of the new line:

y = 2x + b

Use x = -1 and y =3 to find b (or the y intercept ) of the new line:

3 = 2 * (-1) + b

3= -2 + b

b=5

Therefore, the equation of the line passing thru (-1,3) with the same slope as that of y = 2x + 2 will be:

 

 

y = 2x + 5

The population grew to 1,381 people in 1995, and in 1996 the population of Amuel reached 1,519 people. Assume this rate of growth continued until the factory closed in 2007. How many people were living in Amuel when the factory closed? Explain. Round to the nearest whole number, if needed.

Step-by-step explanation:

so if in 1994 it was = 1,256

1995 =  1256 +  x  = 1,381     {x is 125}

1996 =  1381  +  x  = 1,519     {x is 138}

2007 = it is eleven years from 1996 to 2007 so take the average of the both digits which we will find through adding both the x quantities and dividing it with 2 the answer is 131.5. back to 2007, so multiply 11 with 131.5 which is 1,446.5. now add 1,446.5 to 1519

Answers

Answer:

Step-by-step explanation:

We can find this by x=-b/(2a) where a = -2 and b = 105:

x = -105/(2)(-2)

x= -105/-4

x= 105/4

We put this value of "x" into the original formula to find out the value of "y"

y = -2x^2 + 105x - 859

y = (-2)(105/4)^2 + 105(105/4) - 859

y = -1378.13 + 2756.25 - 859

y = 522.12

Therefore, the maximum profit would be $522.12
